DETAILED DESCRIPTION

With reference to the drawings wherein like numerals represent like parts throughout the several figures, a representative railing unit for which several embodiments of a connection system are employed in installing the railing unit is designated generally by the numeral 10. The railing unit comprises a plurality of longitudinally spaced parallel balusters 12 which are secured in position by attachment to an elongated top rail 14 and a parallel elongated bottom rail 16. It will be appreciated that the balusters 12, the top rail 14 and the bottom rail 16 may have various forms and configurations, and railing unit 10 is intended to be exemplary of and representative of various possible embodiments.

Railing unit 10 mounts to upright support posts designated generally by the numeral 20. The support posts 20 may also assume various configurations, and the support posts 20 are intended to be exemplary or representative of various possible embodiments.

Various connection systems are employed to install the railing unit 10 so that it is firmly and rigidly secured to the support posts 20. It will be appreciated that typically, there will be multiple railing units 10 and a multiplicity of support posts 20. The various disclosed connection systems will be described with respect to a single railing unit 10 and a pair of support posts 20. It will be appreciated that the connection systems are easily and efficiently implemented, present a pleasing aesthetic appearance and provide a high degree of structural integrity.

One connection system involves various installation stages designated generally by the numeral 100 and a letter and is illustrated in FIGS. 1-3. A second connection system embodiment involves various installation stages designated generally by the numeral 200 and a letter and is illustrated in FIGS. 5-9. A third connection system embodiment involves various installation stages designated generally by the numeral 300 and a letter and is illustrated in FIGS. 12-15. It will be understood that for purposes of description, each of the connection system embodiments 100, 200, 300 are illustrated in conjunction with essentially the same railing unit 10 and the same support post 20. Typically, the railing unit 10 and the support post 20 are wood products, although other materials may also be suitable. The connection systems are also applicable to non-standard railing geometries which involve non-perpendicular angles and multi-level railing configurations.

With reference to FIGS. 1-3, connection system 100 involves connecting balusters 13 which are preferably initially separate from the railing unit 10. Balusters 13 are similar in shape and dimensions to balusters 12 and may be conceptionalized as an extreme end baluster of the railing unit 10. Each connecting baluster 13 includes longitudinally (vertically when installed) spaced sets of predrilled bores 30, 32.

The connecting balusters 13 are each attached in an upright opposed orientation to each of the support posts 20 with 3-4 fasteners 40 which are secured through bores 30. With reference to FIGS. 4A and 4B, the fasteners 40 are preferably Cortex® hidden deck screws manufactured and marketed by OMG, Inc., of Agawam, Mass. Plugs 44 (FIG. 4B) are installed over the fastener heads to present a smooth finished appearance. The plugs 44 are also preferably Cortex® plugs manufactured and marketed by OMG, Inc., of Agawam, Mass. and described in U.S. Pat. No. 8,104,248. Other fasteners and plugs can also be used.

The top rail 14 of the completed hand rail assembly 10 is suspended atop the mounted balusters 13 and the bottom rail 16 is rotated into place, as best illustrated in FIG. 2. A fastener 42 is installed through a bore 32, into the interior strip of the top rail of the baluster joint, and a fastener 42 is installed through a bore 32 into the interior strip of the bottom rail 16 of the baluster joint, as best illustrated in FIG. 3. Plugs 44 are inserted at the end of the bores over the fastener heads to provide a finished appearance.

In an alternative connection system, the post mounted balusters 13 are installed to the posts 20 as previously described. However, the top rail cover 15 is left off or removed during the initial assembly. The remaining components of the rail unit are rotated into position. A fastener is installed vertically down through the top rail and into the previously mounted baluster 13. The rail is covered by the top rail cover 15 and fastened into place from underneath between the previously installed baluster 13. The bottom rail/baluster connection is completed, as previously described.

With reference to FIGS. 5-9B, connection system 200 employs three connection components 50, 60 and 70. Component 50 (FIG. 5) is an upper post mounting clip which is preferably formed of metal. The upper post mounting clip 50 is fixed to the support post 20 with two fasteners 46 which are inserted and driven through openings 51 of mounting plate 52, as best illustrated in FIG. 5. The bracket 50 has three outwardly biased retention tabs 54, 56 and 58 which integrally extend from the plate 52.

Component 60 (FIG. 6) is an upper rail mounting bracket which is formed from plastic and is configured to accept a metal mounting plate 62. Component 60 also has a receiving recess 64 defined by three sidewalls 65, 67 and 69 which are complementarily configured to be engaged by the outwardly biased retention tabs 54, 56 and 58, respectively, of the support post clip 50. In some embodiments, the sidewalls form retaining grooves which receive and retain the ends of the tabs.

The upper rail mounting bracket 60 has a forward flange-like sleeve 66 which is inwardly complementary in shape to the exterior longitudinal surface or sectional profile of the top rail 14. The sleeve 66 is installed over each end of the top rail 14 and secured by three fasteners 46 driven through openings 61, 63 of the plate 62 and the bracket 60. The fastener heads engage the metal plate 62.

It should be appreciated that in some embodiments, the component 60/mounting plate 62 is an integrated one-piece configuration wherein component 60 is overmolded to retain the metal mounting plate 62. In other alternatives, the metal mounting plate 62 is essentially not required, and the upper rail mounting bracket essentially comprises a one-piece plastic component defining the recess 64 and sidewalls 65, 67 and 69 and having a sleeve-like portion which is complementary to the exterior profile of the rail and is closely received and mounted over the end of the rail 14.

The lower rail mounting bracket 70 (FIG. 7) has a sleeve 76 configured to be complementary to the exterior profile of the bottom rail 16 and has an offset extension 72 with an opening 74. The bracket 70 is slid onto the bottom rail 16 in a force-fit-type engagement. Bracket 70 also has a medial panel 78 with an opening 79. A fastener may be driven through opening 79 into the end of the bottom rail to secure the bracket 70 to the rail 16. The lower rail mounting bracket 70 is preferably formed from plastic.

For connection system 200, the top and bottom rail pieces are preferably cut ½ inch shorter than the typical span between the mounting posts 20 to accommodate the dimensional constraints presented by the brackets 60 and 70.

The entire rail unit 10 with the opposed pairs of mounted brackets 60 and 70, as best illustrated in FIGS. 8-9, is then dropped into place between support posts 20. Each upper rail mounting bracket 60 nests onto and is supported on the upper post mounting clip 50 and engaged by tabs 54, 56 and 58 (see FIG. 9A). The tabs 54, 56 and 58 resiliently engage the sidewalls 65, 67 and 69, respectively, of the bracket 60. The lower bracket 70 essentially self locates adjacent the support post 20. Each lower mounting bracket 70 is then attached to each of the posts 20 by a fastener 46 secured through opening 74, as illustrated in FIG. 9B.

It will be appreciated that the mounting brackets 60 and 70 may be modified to accommodate non-standard angled configurations, such as may occur on an octagon-shaped deck, for example, or multi-level railing configurations, such as may occur for stairways or for multi-level applications. For such applications, the upper mounting clip can be modified by a medial angle section to extend the forward receiving cavity and to angle same relative to the sleeve 66 at the appropriate angle. The lower mounting bracket may also be extended forwardly and include a medial angle section oriented at the appropriate angle.
